In 2000 my first book O lugar da crítica. Ensaios oportunos de arquitetura was published. It gathered some texts written as a journalist and architectural critic during the last decades of the 20th century. And it ended a cycle and opened another: then after twenty years of professional activities I decided to fully embrace the academic world. In this century being a professor and a researcher became my main activity. After another twenty years this new book presents a part of my activities collecting some unpublished and out-of-print texts.
